KFDA-licensed polylactic acid fillers AestheFill are the results of years of development by South Korean research bio-venture company Regen Biotech, Inc. The company is engaged in biotechnology and tissue engineering. Poly-l-lactic acid PDLLA (Poly-D, L-Lactic Acid) is the main component of AestheFill and PowerFill. Due to the unique combination of D- and L-lactide, the AestheFill injections result in new collagen formation, resulting in tighter skin, natural volume replenishment, and contour restoration. It’s widely used for treating scars. PowerFill is a PLA-based filler that’s recognized as a new and safe technique used to increase the volume of the buttocks and the circumference of the penis.
